[Knitting A Conundrum]

You might not envy me the pay...since it's mostly volunteer work...today I was cataloging articles from the early 70s when they were learning to do satellite analysis of environmental things, like tree health.

The pay would be good, too...at least I would learn something new. *sigh*

"... when they were learning to do satellite analysis of environmental things, like tree health."

We'll be using multi-spectral analysis in our mapping of Mars and the asteroids, which was pioneered in those days.

I used something similar, in a document restoration with a scanner, by selecting the frequency of light to which I wanted the scan to be sensitive. It worked.
